After Bangkokians got to enjoy some fresh and clean air for a couple of days, the pollution is rolling back in.

50 areas in the capital city, including the central areas like Pathumwan, have Air Quality Index (AQI) numbers ranging from 151-200  – which is considered unhealthy.

Yesterday, the PM2.5 dust levels reached up to 81 microgrammes per cubic metre of air over the course of 24 hours. This number is higher than the Thai-set safe margin of 50mcg – twice of WHO’s standard number of 25mcg. 

Besides Bangkok, Northern provinces are suffering from the high smog as well. 


What is PM2.5?


PM2.5 is an atmospheric particulate matter from various sources like forest fires, planes, and agricultural burnings. Its size is less than 2.5 micrometres – hence its name, making it transmit into our bodies easily.

With the particles being so fine, humans and animals can inhale them into our systems and into our lungs. This study shows that long-term effects include heart disease. 

It can also trigger or worsen chronic diseases like asthma and other respiratory problems.


Check air quality index levels regularly

Sometimes, checking the surroundings with your eyes is not enough. Keep up with AQI in your area on AirVisual, which will provide you with real-time data. For convenience, you can also download their application on your phone.

You can also check the air quality of your destinations out of Thailand.


Find the right mask to wear outdoors

Not every mask can filter out PM2.5, not even a medical mask we’re familiar with. The most common and affordable one is 3M N95 masks, which have been tested and found to be effective.

When you’re wearing a mask to protect yourself from COVID-19, also consider wearing ones that can shield out the PM2.5 too – stay strong folks.
